Large Aperture Gamma Ray Burst Observatory (LAGO)
The LAGO project is an international astrophysics and astroparticles project led by 23 institutions in 9 countries. It was founded in 2005 in a workshop in San Carlos de Bariloche, following a proposal presented at the RICH2004 in Mexico.
The main idea of the project is to operate low cost Water Cherenkov Detectors (WCD) at high mountain sites to look for Gamma Ray Bursts and study solar activity through the modulation of cosmic ray flux. The first detector was built in Bariloche in 2005 and the first to operate at high mountain site was built in Chacaltaya, Bolivia, in 2006.
In Bariloche we operate two WCD, a 2m2, 1.5m tall one, Nahuelito, and a 2m2, 75cm tall, Boyita. They are used for software development, and their counting rates are used to study the cosmic ray modulation produced by solar activity. Nahuelito is also used to train students at the Instituto Balseiro, measuring the muon decay time.
The main web page of the project, currently in remodeling, is at CEVALE2 in Colombia.
LAGO DAQ electroncis
The first DAQ electronics of LAGO was based on the prototype electronics of the Pierre Auger Observatory. Thanks to an ICTP grant in 2010, a new DAQ electronics was designed, tailored for LAGO. This work was mainly done at the DPR lab, in collaboration with the Puebla group of Mexico.
The new electronics is working on both DPR lab detectors, Nahuelito and Boyita, since December 2011.
